Hi Linus !

This series fix a nasty issue with radeon adapters on powerpc servers,
it's all CC'ed stable and has the relevant maintainers ack's/reviews.

Basically, some (radeon) adapters have issues with MSI addresses above
1T (only support 40-bits). We had powerpc specific quirk but it only
listed a specific revision of an adapter that we shipped with our
machines and didn't properly handle the audio function which some distros
enable nowadays.

So we made the quirk generic and fixed both the graphic and audio drivers
properly to use it.

Without that, ppc64 server machines will crash at boot with a radeon adapter.

Note: This has been brewing for a while, it just needed a last respin which
got delayed due to us moving ozlabs to a new location in town and other such
things taking priority.

Cheers,
Ben.
